TATAM RCT Demonstrates Superior Angiographic Outcomes with Transvenous Embolization in Stroke Management – Stroke AHA/ASA
Stroke AHA/ASA posted on X:
“RCT results show that transvenous embolization is more effective than transarterial embolization in terms of angiographic results at 3-6 months, with comparable morbidity.”

Brief Analysis: TATAM RCT Findings
The TATAM randomized controlled trial compared transvenous embolization (TVE) versus transarterial embolization (TAE) in patients requiring endovascular intervention for cerebrovascular malformations.
Key Finding:
TVE demonstrated superior angiographic occlusion rates at 3–6 months follow-up, indicating more effective lesion closure.
Clinical Impact:
Despite a more technically complex route, TVE maintained morbidity rates comparable to TAE, supporting its safety profile.
Implication:
TVE may become the preferred embolization strategy for select cerebrovascular lesions, offering enhanced efficacy without increased risk.
